Summary:A method for controlling read velocity in a disk device is provided. When reading data on the disc, the method first reads each SYNC of blocks to form an ECC code, read data to decode, and checks and corrects decoded data to generate decoded errors. The type of decoded errors are classified and counted to form reference parameters of a rule base. A fuzzy engine checks if the counting number exceeds the threshold of the parameter, and executes the operation of the rule to control read velocity and enhance the data transfer rate in the disk device.
